power board

Hi since I changed the model I wanted to know the power button and the reset where I could connect it on a model scph 90004 please help me. :( I wanted to know if this switch scheme is okay obviously and a ps2 slim is also okay for a super slim?

Okay so I'm making my first portable console, (a gamecube obviously) and I am not sure what I should do with the power board! So here are my questions: 1. How do I connect the battery to the power input? 2. Will the battery power button turn on power or will the power board button turn...
